   trang của trình duyệt, chồng chéo với hiệu ứng document.startViewTransition() đã tự

/* ===== Sửa: 3 thẻ "Xem trước miễn phí / Thanh toán an toàn / Hỗ trợ khi có lỗi" không có hiệu ứng hiện lên =====
   Nguyên nhân: quy tắc `.about-point{ transition: box-shadow, border-color, background }` nằm SAU `.reveal`
   nên ghi đè mất transition của opacity/transform/filter → thẻ "nhảy" ra ngay thay vì mờ dần + trượt lên.
   Cách sửa: gộp cả hai danh sách transition cho thẻ đang có .reveal (hover vẫn mượt như cũ). */
